ELECTRIC OVEN FOR HAIR.

Application filed September 28, 1922. Serial No. 591,051.

T 0 all whom it may concern:

Be it known that I, ALICE M. \VRIGHT, a citizen of the United States of America, residing at Detroit, in the county of Vayne and State of Michigan, have invented certain new and useful Improvements in Electrio Ovens for Hair, of which the following is a specification, reference being had therein to the accompanying drawings.

This'in'vention relates to an oven adapted to be used in imparting what is known as a ermanent Wave or curl in hair.

it has for its primary object to provlde a heater adapted for use upon hair upon the head of the operator.

Another object of the invention is to provide a heater capable of being readily modified for use in various locations with curls orwaves of various forms and with locks or tufts of hair of different sizes.

A further object of the invention is to provide a heater in which hair wound upon any suitable form of hair curler may be subjected to moisture and heat, but in which steam roduced .may readily escape.

Furt ier objects ofthe invention will appear in the specification, the drawing illustrating a preferred embodiment of the invention, together with certain desirable modifications and attachments.

Figure 1 is a perspective view of the device as it appears while in use;

Fig. 2 is a perspective view. parts being broken away of one of the sections with the removable heating plate detached;

Fig. 3 is a perspective view of a preferred form of heating plate shown in position in Fig. 1; 1

Fig. 4 is a side elevation of a modified. form of plate;

Fig. 5 is a perspective view illustrating a preferred form of cloth and curler for use with the oven;

Fig. 7 is a plan view of an attachment shown as secured to one ofthe oven sections;

Fig. 8 is a side elevation showing two of the attachments illustrated in plan in Fig. 7, secured in position upon the heater, and

Fi 9 is a section of a modified heating mem er. 7

The heater comprises a pairof hollow shells 1, 2, preferably made of aluminum or of one of its alloys. Secured to each of theseshells 1 and 2 or preferably formed integral therewith are handle members 3 and 4 to which may be secured handles 5 and 6 of wood or other heat insulating material.

As illustrated most clearly in Figs. 2 and 6, the shell 2 is provided with a lining 7 of asbestos or other heat insulating material and the top of the shell is preferably provided with -a cover plate 8 of thin metal secured within the shell in any suitable manner. Within the formed by the lining 7 and the cover plate 8 is mounted an electric heating elementfi of any suitable constructionhaving outside terminal posts 10, 11, which maybe connected by wires 12 with any suitable source of electricity. Upon the confronting faces of these heating sections are secured plates 13, these plates being held in position by any suitable means as by spring clips let engaging within suitable depressions 15 in the ends of the plates.

In Fig. 5 a curling pin 16 is shown in which a central wire 17 lies between two outer parallel wires upon which the hair may be wound and held by the engagement of the end of the .wire 17 'with a loop portion 18 of the curler. The wire 1? extends through an open ended pocket formed at one end of a cloth 19. After the hair is wound upon the curler, the moistened cloth 19 is secured to the wire 17 which is then placed within the loop 18.

box-like structure The cloth is then wrapped around the hair twisted upon the curler. The .roll formed by the hair andcloth is then grasped be tween the heating plates 13, the temperature of which is suiiicient to raise the water in the cloth 19 almost to the boiling point. Any steam that may be formed can escape at the sides or ends of the oven constituted by the space between the heating plates, and by proper regulation of the temperature no injury will be done to the hair. The handle members 3 and 4 are normally forced apart by a spring 20 so that when the device is applied to the hair the plates 13 are separated to receive the hair with its wrapping and the operator may apply as much pressure as is desired by pressing together upon the handles 5 and 6.

While the plates 13 ar e preferably vided with a concave face as shown in 3, it will be evident that plates having different configurations may readily besubstituted therefor. In 'Fig. 4, plates 21 are shown having corrugated interfitting faces suitable for use upon a strand of hair which has not been wound u on a curler, and in such cases the damp c oth may be omitted if desired. a

In Fig. 7 a plate 2 2 is shown attached by spring clips 23' to the shell 1. This plate 23 1 may consist of a thin sheet of aluminum hair treated at a singleoperation.

It Will be observed that the device described is intended to be held within the hand of the operator, and that its structure renders it particularly suitable for non-professional as distinguished ,from previous devices which are suitable for'use only by an operator other than the person whose hair is being treated;

It is. obvious that by means of this device I the hair may be subjected either to moist or dry heat and it is also obvious that by suitable modification of the configuration of the plates 13 the device may be adapted to any type of curler though it is also obvious that by the use of plates having an undulating surface such as shown in Fig. 4, the use of such a curler as shown in Fig. 5 may be dispensed with. While'in the preferred embodiment of my invention, the heating mem bers 1 and 2 have been described as hollow shells containing electric heating elements, it will be obvious that when electric current is not available, the device may be made with the-members "1 and 2 of solid metal as shown in Fig. 9 which can be heated over a'lamp, a gas jet, an alcohol burner or by any other source of heat, the removable plates and attachments evidently having the 1 same form and function as when the electric heating elements are used. device of the charact r herein shown and described can be use upon short hair as well as upon long hair, though when the hair is short it will be moreconvenient to coil the hair on insulated wire from the ends of the hair toward the head and then to' grasp the coils with the portion of the tool opposite the handles. The .use of curlers worn over night is avoided by the apparatus herein described, and asbefore stated, it is primarily designed for use in the home be cause of its convenience for use upon the head of the operator.

It is very evident that many modifications may be made in the structu're'of my device without sacrificing any of its advantages or departing from its principle of operation. It is therefore intended that the invention shall be claimed broadly within the legitimate and valid scope of the appended claims.

I claim 3 l. A heater comprising two sections having handle portions crossing each other and pivotally secured together, a heating element mounted within each section, and a heating plate detachably secured upon each of the opposing surfaces of said sections.

2. A heater comprising a pair of hollow shell sections each havingan insulating lining and a heat conducting cover plate, a pair of plates detachably mounted upon the hollow shells adjacent to said cover plates,

and resilient meansnormally operative to hold said plates apart from each other.

3. A heater comprising a pair of plates having complementary surfaces adapted to receive a fold of hair therebetween, said plates being separated from each other at all points whereby vapor may freely escape from between the plates.

4.- A heater comprising a pair of handle members pivotally secured to each other in crossed relation, a pair of hollowshells upon the portion of the handle member beyond said pivot, each of said hollow shells con-' taining a heating element, the plates having curved opposing faces detachably secured upon the confronting surfaces of said hollow p shells, and means for supplying a current to each of said heating elements.

5. A heater comprising two sections having handle portions crossing each other and pivotally secured together, and a heating plate detachably secured upon each of the opposing surfaces of said sections.

' In testimony whereof I aflix my signature in presence of two witnesses.
